- To all wko'rn it may concern:

Be it known that I, EDGAR H. BERRY, citizenof the United States, and resident of the borough of Brooklyn, city of'New York, in the county of Kings and State of New' York, have .invented certain new and useful Improvements in-Type-Wrltlng Machines, of whic h the followlng is a. specifi-' cation.

My invention relates to typewriting machines and more particularly to aper feeding and controlling devices, an the main.

object of said invention is to provide improved 'devices of the character specified.

To the above and other en'ds which will. hereafter appear, my invention consists of :the features of construction, arrange:

ments of arts and combinations of devices to be hereinafter described-and particularly tion showing the leading edge stops and the manner of mounting the same. Fig; 5 is a fragmentary detail perspective view of the platen frame and some of the parts carried thereby. Fig. 6 is a detail fragmentary perspective view showing a portion of the platen frame and the means for supporting the paper apron. Fig. 7 is'an enlarged fragmentary detail verticalsectional view taken transversely throu h the platen and showing the leading edge stops, the detent for the platen and some of the associatedparts. Fig. 8 is an enlarged fragmentary perspective View of the leading edge stops and the means for supporting said stops. Fig. 9 is an end' elevation showing the margin feed rollers and their support, the platen being 1 front face of the Jlaten on the line w though shown diagrammatically in this view.

I have shown the devices of my invention applied'to a front-striketypewriting machme inwhich the types strike against the it should be un erstood that from certain aspects ofmy invent-ion the devices maybe embodied in varioust styles of typewriting machines. v

The frame of the machine comprises corner posts 1 and a top plate 2. Flxed guide rails 3 and 4 are su ported on posts 5 which extend upwardly. rom the top plate. The

rails 3 and 4 are grooved for cooperation with anti-friction balls or rollers 6 which 'are also received in forming the rear-yen front cross bars respectively of the carriage or truck, said. bars ooved rails-7 and 8 being united-by end bars 9. The'end bars ;,9- have dgpending arms 10.to which the for-' s of the links 11 are pivoted'at 12, the rear ends of said links being pivoted {Ward 811 at 13 to the end'dplates 14 of the platen frame. Correspon parallel links 15 are pivoted to the platen rame at 16 and to the carriage at 17. Upon reference to Fig. 5 it will be seen that the end lates 14: of the platen frame are connected y cross bars 18 z and 19 and that a laten A is supported on a platen shaft whic is journaled in bearing openings in the end plates of the-platen frame. Angular brackets 20 are secured. to or formed as a part of the cross bar 18 and are provided with bearings 21 for. a rock or release shaft 22 which is likewise pivotally supported at its ends on the end plates 14 of the laten frame. .A coiled spring 23 surroun s the rock shaft 22 near one end.-

thereof and is secured at one end .to a p n 24 which extends from the left-hand end plate 14, the other end of the spring being secured at 25 to a crank arm 26 provlded'at its upper end with a finger piece 27.

Hubs 28 surround the'rock shaft 22 and,

are adjustably connected thereto by set screws 29. Eaehof these hubs has a depending crank arm 30 which cooperates with the upper arm 31 ofa three-arm lever pivoted on a rod 31 supported by the angular brackets 20. The de ending arms 32 c said to rece ve parallel shafts supports a rear set ofmain feed rollers 41,

ment or stop 43 formed as a part of an an-- gular' bracket 20.

From the foregoing description it will be understood that the pressure of the springs 33 is exerted on the an a1 levers 31--32-35 to force thefeed rol ers into contact with the platen or the paper thereon. When the finger piece 27 is moved rearwardly the rock shaft 22 is turned to move the depending crank arms 30 forwardly, thus rocking the angular levers on their pivots against the tension of thesprings 33, thus causing the feed rollers to be moved away from the platen. When the pins 4:2 which are located forwardly of the pivots 36 are brought into contact with their cotiperating stops 43, a further movement of the forward set of feed rollers away from the platen is prevented, although a continued movement of the rear set of feed rollers may take place to enable the main feed rollers to be moved at a considerable distance from the platen to prevent them from obstructing the paper in its movement around the platen while the forward set of feed rollers are maintained but a slight distance from the platen.

A paper apron 44 is provided with depending lugs {15 at the front and rear portions thereof (see Fig. 6) the lu sbeing perforated to receive screws 46 whic take-at their threaded .ends into segmental bearing ieces 47, the stems of the screws extending reely through slots 48 in corresponding segmental pieces or links $9. The construction is. such that the paper apron ma receive an adjustment circumferentially. o the platen on the links or segmental pieces49 by which the paper apron is supported to effect an adat 50 to a downwardly extending link 51' pivoted at 52 to a lug 53 formed on and extending outwardly from an angular bracket 20 as shown in Fig. 5. Each of the links 49 is also pivoted at 5 1 to a link 55, the lower and of each of said last mentioned links being pivoted at 56 to a depending arm 57 of an angular on the cross bar. The upturned en lever pivoted on the pivot 1 these members are forme rod 31, the other or forwardly extending arm-58 of each of said angular levers extending forwardl and upwardly and hearing at 1ts free en againstthe bottom of the paper apron near the forward edge thereof in order to press it toward the platen. The arm 57 of each of the angular levers is connected to a contractile spring 59 secured at its forward end to the cross bar 18. The

pressure of these s rings 59 is therefore exerted not only to orce the forward ends of the arms 58 against the paper apron but also to force the rear portion of the paper apron toward the platen thro\1'gh the interposed links 55.

From an inspection of Figs. 3 and 6 it will be seen that the, pivots of the links 51 and 55 are in different planes and that the forward'set of links 51 are shorter than the rear set of links 55. The construction is such that a differential movement of the .paper apron is afforded, the rearportion of the paper apron receiving a greater extent of movement thanthe forward portion thereof as it is deflected away from the platen in order to prevent the pa er from being choked between the, platen and the paper apron.

It will be seen that a line drawn through the pivotal points of connection 50 and 52 of each link 51 is arallel, or substantially parallel, with a. l1ne drawn through the points of pivotal connection 54 and 56 of the associated link 55 so that the links 51 and 55 are in effect parallel links and I will refer to them herein as such or will refer to them as substantially arallel links.

From an inspection of igs. 3, 4; and 8 it will be seen that the release or rock shaft 22 is provided with depending hanger arms 60,

that project forwardly at the lower ends thereof where they are riveted at 61 to a crossbar 62. The cross bar is rovided with substantially U-shaped metallicpieces or members 63 each having a slot 64 that extends transversely of the platen and adapted to receive the stem of a screw 65 threaded at its end into openings in the cross bar 62. The washer 66 is inter osed between the head of the screw 65 and t e member 63 so as to clamp the member in its adjusted (position 5 67 of the member 63Mconstitute' leading edge sto s for coiiperation with the leading edge of tiie paper as it is introduced into the machine, as will hereinafter more clearl appear. The portions 62 of the bar 62 against which the central portions 63 of the members 63 bear are ,elevated' above the upper face of the bar 62 so that the members 63 to. either side of the-bearing portion 63* are free from contact with the bar '62 in order to afford movements of the free ends of the members 63 toward the bar against the pressure of the-members. 63, it bein understood that of resilient metal.

. Each of the hangers 60 is The object of this construction is to provide resiliently mounted leading edge stops which are adapted to be deflected against their spring pressure when they are brought againstthc platen with undue force. Two of the members 63 are shown in the present instance though it should be understood that any desired number of such members may be em loyed. The construction is such that an ad ustment of the members 63 on the bar 62 may be effected either circumferentially of the platen or around the screw 65 as pivots in order to bring-the leadin r edge stops into alinement or to raise or lower them relatively to the main set of feed rollers 41. rovided with a bearing 68 by which it is oosely mounted on the rock shaft 22 and a pin 69 projectsfrom the end of each bearing 68 and is received in a cut-out or opening 70 in the hub 28 of the associated crank arm'30 as shown in Fig. 4 in order to provide a pin and slot connection between the rock shaft and each of the hangers to afford a limited independent movement between the rock shaft 22 and the hangers 60. The pins 69 are each normally maintained in contact with one of the end walls of the slot 70 by a coiled spring 71 which surrounds the shaft 22 and is connected at one end to the associated hanger arm and at the other end to a sleeve 7 2, the sleeve being secured to the rock shaft 22 by a set screw 73. These springs, 71 nor mally, maintain a fixed relation between the hangersGO and the rock shaft 22. The con- 'struction is such that a rearward movement of the finger iece 27 is effective to project the so-called eading edge stops 67 through apertures on the paper apron and into contact with the platen before the "main pa er feed rollers 39 are moved out of contact with the platen. VVhen, however, the leading edge stops are brought into contact with the platen a further movement of the finger piece 27 isefi'ective to turn the rock' shaft 22 independently of the hanger arms 60 and to move the main pa er feed rollers 39 away from the platen. 1 these means the stops are interposed into t e pat-h of the paper before the main paper 'feed rollers are withdrawn fromthe platen and there is an assurance of the proper-arrest of the paper by the leading edge stops. During thereturn movements of the parts to normal position the. leading edge stops remain in contact with the platen and in the path of the paper until the main aper feed rollers are moved back to norma position and into enga ement with the paper when'the leading edge stops are move to normal p sition. These results are produced by' the limited inde-.

pendent movement between therock shaft 22 and the hanger arms 6 84', so far as my springs 71 should be greater than that of the members 63 the members 63 will be deflected against their inherent spring pressure and will not be projected with undue force against the face of the platen.

From an inspection of Figs. 1, 2, 3, 7 and 9 it will be seen that a supporting bar 74 is supported on the end plates l4-of the platen frame for pivotal movement around the longitudinal axis of said bar. The bar is supported above the platen near the rear side thereof where the paper is introduced into the machine and in such a position that the aper, as it leaves the printing line,'may be irected by the paper feeding devices over the bar as will hereinafter more clearlyappear. The supporting bar 74 is angular in cross.section and cooperates with sup ports 75 sha ed to conform to the cross section of the ar on three sides thereof and each support is provided with a leaf friction spr1ng.76 (Fig 9) which bears against the under face of the supportin bar and retains the; support against accidental displacement from the position to which it may e adjusted along the supporting bar. Two supports 75 are rovided, one or use near eachend of the p aten, and both of said supports and thepaper feeding devices carried thereby are the same so that the description of one up lies to the other and but one will be desc'ri ed. Each support carries. forwardly extending ears or arms 77 which re ceive a pivot 78 for a forwardly extending rigid hanger 7.9 that has an inwardly extending off-set projection 80 with arms 81 and 82 extending therefrom. A leaf spring 83 is secured b a finger piece 84 to each support 75 and hears at its free end against the associate han er 79, tending to force the free end of thei A pivot 85 extends between the arm 82 and the body portion of the hanger 79 and constitutes a pivot for-a paper finger 86. A coiled spring 87 surrounds the pivot 85 and bears at one end. a ainst the paper finger and at theother enc l against the off-set 80. A pivot 88 extends between the hanger 79 and the arm 81 and carries a margin feed roller 89 and spacing sleeves 90 which surround the pivot, preventan axial movement of the margin 'feed roller on its pivot. The

. paper as it leaves the platen scale is directed upwardly'and rearwardly under the paper finger and margin feed rollers and over the 'supportin bar 74 so that said bar does not obstructt e operators view of the writing. While I have described in detail the paper finger andfeed roller and the manner of- -connecting the same to the supports 75 and the mounting of saidsupports on the bar resent invention is concerned, any suitab e paper feeding devices may be employed. The specific construction of these paper feeding devices and the mananger toward the platen.

ner of mounting the same are not of my invention but are the invention of Oscar Woodward and are disclosed in an application Serial No. 404,814, filed by him on the second day of December 1907 The finger pieces 84 which facilitate an adjustment of the carrier 75 along the supporting bar 74 likewise constitute means by which the supporting bar 74 may be turned on its longitudinal axis. a y

In order to retain the paper feeding devices supported on the bar 74 either in their operative or inoperative positions or in or out of cooperative relation with the platen and to vary the extent of pressure of said devices on the laten, I.have provided devices which w' now be described. Thus,

a disk 91 is securedto the supporting bar 74 near one end thereof for cooperation with a spring detent"92.secured to the underside of an end foot piece on the cross bar 19 by a screw 93. This same screw secures one end of a spring 94 to the cross bar,.the other end of said spring 94 carrying a detent roller 95 which cooperates with t e teeth ofa line spacing ratchet wheel 96 in the usual manner. Upon'reference to F ig. 2 it will be seen that the spring detent 92 is bent laterally at the forward end portion thereof and is bent up at its end for cooperation with the disk or bearing piece 91 which is situated to the right of the line spacin wheel on the supporting bar 74. The dis has two notches 97 e and 98 in the periphery thereof for cooperation with the spring detent 92. When the partsare in the normal position shown in Fig. 9 the detent 92 engages the notch 98 and holds the supporting ar 74 in the position-where the springs 83 bear upon the hangers in orderto effect the normal 'amount 1 of pressureupon the margin feed rollers.

If, however, anadditional amount of pressure is desired upon the margin feedrollers either of the finger pieces 84 may be moved forwardly to effect a slight turning movement of the supporting bar 74 on its longitudinal axis to disengage the detent 92 from the notch 98 and cause it to en age in.the forward notch 97. The bar un er this adjustment will be held in such position that the spring 83 will be flexed to a greater extent and an additional pressure of the springs on the hangers of the margin feed rollers will be produced to press said feed rollers with g eater force against the laten or the paper thereon. If the operator s lould desire to throw the paper feeding devices out of operation or away from the platen it is merely necessary to turn either of the fingergers away from the platen and out of cooperative relation therewith.

In order that one platen may be readily substituted for another when desired, I have provided the spring 94 of the roller detent with a yoke-piece 99 which is riveted to the spring and partly surrounds the bar 74 as s own in Fig. 7. The bar 74 has an eccentric or cam piece 100 which, when in the normal positions of the parts or when the paper feeding devices are in coiiperative re at on with the platen, is in a position such as that shown in Fi 1 where t does not cooperate with the yo e piece 99.

When, however,

the bar 74 is turned to the position shown.

tion disclosed inthe application'of Oscar Woodward hereinbefore referred to.
